Sat, Feb 20, 2010from University of Miami via ScienceDaily: Arctic Glacial Dust May Affect Climate and Health in North America and EuropeResidents of the southern United States and the Caribbean have seen it many times during the summer months -- a whitish haze in the sky that seems to hang around for days. The resulting thin film of dust on their homes and cars actually is soil from the deserts of Africa, blown across the Atlantic Ocean. Now, there is new evidence that similar dust storms in the arctic, possibly caused by receding glaciers, may be making similar deposits in northern Europe and North America...dust activity from the newly exposed glacial deposits will most likely increase in the future in Iceland and possibly from other glacial terrains in the Arctic. ...

That means I'll have to use scarce water resources to wash my car more often!

Fri, Feb 19, 2010from Telegraph.co.uk: Penguins in Antarctica to be replaced by jellyfish due to global warmingThe results of the largest ever survey of Antarctic marine life reveal melting sea ice is decimating krill populations, which form an integral part of penguins' diets.
The six-inch-long invertebrates, also eaten by other higher Southern Ocean predators such as whales and seals, are being replaced by smaller crustaceans known as copepods. These miniscule copepods, measuring just half a millimetre long, are too small for penguins but ideal for jellyfish and other similarly tentacled predators.... Any decrease in sea ice will inevitably affect the delicate balance of the Antarctic marine food chain.
For creatures such as penguins who lives on the melting sea ice, a rise in temperatures will also shrink the size of their breeding grounds. ...

Wed, Feb 17, 2010from Science Daily: Permafrost Line Recedes 130 Km in 50 Years, Canadian Study FindsIn a recent issue of the scientific journal Permafrost and Periglacial Processes, Serge Payette and Simon Thibault suggest that, if the trend continues, permafrost in the region will completely disappear in the near future.... While climate change is the most probable explanation for this phenomenon, the lack of long term climatic data for the area makes it impossible for the researchers to officially confirm this. Professor Payette notes, however, that the average annual temperature of the northern sites he has studied for over 20 years has increased by 2 degrees Celsius. ...

It doesn't sound quite so bad when you say "80 miles." Um, or does it?

Wed, Feb 17, 2010from Woods Hole Oceanographic Institution: Team finds subtropical waters flushing through Greenland fjordWaters from warmer latitudes -- or subtropical waters -- are reaching Greenland's glaciers, driving melting and likely triggering an acceleration of ice loss, reports a team of researchers led by Fiamma Straneo, a physical oceanographer from the Woods Hole Oceanographic Institution (WHOI).
"This is the first time we've seen waters this warm in any of the fjords in Greenland," says Straneo. "The subtropical waters are flowing through the fjord very quickly, so they can transport heat and drive melting at the end of the glacier."... Deep inside the Sermilik Fjord, researchers found subtropical water as warm as 39 degrees Fahrenheit (4 degrees Celsius). The team also reconstructed seasonal temperatures on the shelf using data collected by 19 hooded seals tagged with satellite-linked temperature depth-recorders. The data revealed that the shelf waters warm from July to December, and that subtropical waters are present on the shelf year round.
"This is the first extensive survey of one of these fjords that shows us how these warm waters circulate and how vigorous the circulation is," says Straneo. "Changes in the large-scale ocean circulation of the North Atlantic are propagating to the glaciers very quickly -- not in a matter of years, but a matter of months. It's a very rapid communication." ...

"Subtropical" and "Greenland" should never appear together in a headline.
